Hi Leo10m2010 - Not to worry, our billing does not happen immediately upon usage.

We invoice and charge your credit card on the 1st day of each month for the previous month’s usage. Time zone differences can cause some minor variation in invoice date and time. DigitalOcean bills in USD. To keep our pricing stable and consistent, rather than fluctuating with exchange rates, we do not bill in local currency. Similarly, we do not invoice in local currency. All invoices are in USD.
